Changes in directory llvm/lib/Target/ARM:

ARMISelLowering.cpp updated: 1.4 -> 1.5
---
Log message:

Propagate changes from my local tree. This patch includes:
1. New parameter attribute called 'inreg'. It has meaning "place this 
parameter in registers, if possible". This is some generalization of 
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend. 
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each 
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in 
on first attribute has meaning 'This is hidden pointer to structure 
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to 
FunctionExtraction pass, which relinks all internal-linkaged callees 
from deleted function to external linkage. This will allow further 
linking everything together.

NOTEs: 1. Documentation will be updated soon. 
       2. llvm-upgrade should be improved to translate csret => sret. 
          Before this, there will be some unexpected test fails.
